Abstract

The invention provides an electronic product having a choke device. The choke device comprises a frame, a first rotating member and a second rotating member. An accommodating space with a circular cross-section is formed in the middle part of the frame. The first rotating member comprises a first choke sheet whose bottom is an arc with the middle part protruding downwards and a first pivoting rod arranged on the top of the first choke sheet. Two ends of the first pivoting rod are respectively in pivoting connection with the middle parts on two sides of the accommodating space. The second rotating member comprises a second choke sheet in an arc shape with the two sides bending backwards and a second pivoting rod arranged on the top of the second choke sheet. The top of the second choke sheet is an arc with the middle part protruding upwards. Two ends of the first pivoting rod are respectively in pivoting connection with the parts, close to the tops, on two sides of the accommodating space. The first and second choke sheets droop due to the gravity and obstruct respectively the upper half part and the lower half part of the accommodating space, so that the air backflow is obstructed.

Detailed description of the invention

Refer to Fig. 1 and Fig. 2, for the choke device 10 of the present invention the first better embodiment. This choke device 10 includes framework 12,1 first tumbler 14 and one second tumbler 16.

This framework 12 includes the main body 121 of a cylindrical shape and by the rear and front end of this main body 121 outward extending two plate bodys 125 being parallel to each other respectively. The middle part of this main body 121 is provided with the receiving space 124 that the cross section of a front and back end running through this main body 121 is circle. Each plate body 125 is respectively equipped with a clamping hole 126 in contiguous corner place. The overall dimensions of this framework 12 and the cross-sectional area of this receiving space 124 are identical with the cross-sectional area of the overall dimensions of the fan board 21 of common standard fan 20 and flabellum receiving space 23. The mounting means of this framework 12 is also identical with the mounting means of standard fan 20.

The middle part of the both sides of this main body 121 is respectively equipped with first pivoting hole 122 being connected with this receiving space 124, and the both sides of this main body 121 are respectively equipped with second pivoting hole 123 being connected with this receiving space 124 in adjacent top place. In the present embodiment, this two first pivoting hole 122 and this two second pivoting hole 123 are in same vertical plane.

One first pivot rods 143 that this first tumbler 14 includes one first wind-retarding plate 141 and the middle by the top of this first wind-retarding plate 141 is stretched out to both sides. This first wind-retarding plate 141 is the one or two recurvate arc in side, the plane that top 145 is a level of arc, and bottom 147 is in middle downward projection of arc. This first pivot rods 143 arrives the vertical dimension of the middle of 147 bottom this and arrives the vertical dimension between the plate body 125 of this framework 12 front end less than or equal to this two first pivoting hole 122.

This second tumbler 16 includes the recurvate one second curved wind-retarding plate 161 in both sides and one second pivot rods 163 stretched out by the middle at the top of this second wind-retarding plate 161 to both sides. Bottom 165 level of this second wind-retarding plate 161, the arc that top 167 projects upwards in centre. This second pivot rods 163 arrives the vertical dimension of 165 bottom this and arrives the vertical dimension between the plate body 125 of this framework 12 front end less than or equal to this two second pivoting hole 123.

Refer to Fig. 3, when assembling this choke device 10, make this first pivot rods 143 flexural deformation be contained in this receiving space 124.The two ends of this first pivot rods 143 are respectively aligned to two first pivoting holes 122 of this framework 12, this the first pivot rods 143 elastic recovery makes the two ends of this first pivot rods 143 be respectively clamped into this two first pivoting hole 122, thus being installed in rotationally in this receiving space 124 by this first tumbler 14. This first wind-retarding plate 141 is by the action of gravity vertically sagging lower half being barred from this receiving space 124, and the both sides of this first wind-retarding plate 141 and bottom 147 adjoin both sides and the bottom of this receiving space 124 lower half respectively. This second pivot rods 163 flexural deformation is made to be contained in this receiving space 124. The two ends of this second pivot rods 163 are respectively aligned to two second pivoting holes 123 of this framework 12, this the second pivot rods 163 elastic recovery makes the two ends of this second pivot rods 163 be respectively clamped into this two second pivoting hole 123, thus being installed in rotationally in this receiving space 124 by this second tumbler 16. This second wind-retarding plate 161 is by the action of gravity vertically sagging first half being barred from this receiving space 124, the both sides of the both sides of this second wind-retarding plate 161 and top 167 this receiving space 124 first half adjacent respectively and top, the bottom 165 of this second wind-retarding plate 161 adjoins the top 145 of this first wind-retarding plate 141. By this first, second wind-retarding plate 141,161, entering the distinguished and admirable of this receiving space 124 can be blocked substantially.

Refer to Fig. 4, when this choke device 10 is subject to by bigger wind-force effect before backward, this first, second wind-retarding plate 141,161 forward and is rotated up around first, second corresponding pivot rods 143,163. When wind-force is sufficiently large, this first, second wind-retarding plate 141,161 rotatable 90 degree, now windage is minimum. In the process, this first, second wind-retarding plate 141,161 is all contained in this receiving space 124 all the time, will not stretch out framework 12.

When standard fan 20 fault in the cabinet 30 of an electronic product and when can not find replacement fan, this standard fan 20 can be pulled down and load this choke device 10 with identical mounting means, in Fig. 1 shown in choke device 10 between two standard fan 20. First, second wind-retarding plate 141,161 of this choke device 10 is in natural vertically hang and can stop distinguished and admirable backflow.

If space allows, user can install a choke device 10 in the front end of a standard fan 20, in Fig. 1 shown in the choke device 10 of the leftmost side. When standard fan 20 runs well, first, second wind-retarding plate 141,161 of this choke device 10 is rotated 90 degree by sufficiently large wind-force effect forward upward, does not affect the air-out of standard fan 20. During standard fan 20 fault, this first, second wind-retarding plate 141,161 returns to naturally vertically hang, thus distinguished and admirable backflow can be stopped.

Refer to Fig. 5 and Fig. 6, for the choke device 50 of the present invention the second better embodiment. Compared with choke device 10, the first wind-retarding plate 141 of the first tumbler 14 has been replaced to the first wind-retarding plate 541 convex under flat semicircle arc by this choke device 50.
